DPD Productions offers three antenna models for MURS radio (Multiple Use Radio Service), shown below. These models are specifically tuned to work on the MURS frequencies of: 151.820, 151.880, 151.940, 154.570, and 154.600. These models can potentially be used with the new MURS radio band based intercom and security devices, such as the Dakota Alert base and remote units... to help extend range. They can also be used with MURS based dog tracking devices, such as the Garmin Astro or Tracker Maxima. If you have basic questions about antennas, please try checking the FAQ pages.
